Alice G LOO Bob Let's revisit the simultaneity problem from worksheet 11. To make things concrete, we'll include specific numbers. Bob is standing on the ground watching Alice go by in a high-speed train. As seen in Bob's reference frame, Alice is traveling to the right at speed v = +0.80c. As measured in Bob's frame, Alice's rail car is 12 m long. Alice is sitting in the exact center of the train car. At the instant that the Alice...

1. A rectangular coil of wire with sides W and H has N turns. To its right is a region of uniform constant magnetic field of magnitude B. The width of this region, L, is greater than W. The direction of the field is out of the page Starting outside the region of magnetic field, the coil moves with constant speed v to- wards, into, and out of the region of field, as shown. A light bulb of resistance R...

The simple oscillating circuit shown above is made from a parallel plate capacitor connected to a solenoid. The capacitor has plates 3.0 cm x 6.0 cm separated by 2.0 mm and filled with a material with a dielectric constant x- 8.0. The air-filled solenoid is 12.0 cm in length, with a diameter of 2.5 cm, and wound with 150 turns. The capacitor is charged to 0.25 uC, and the switch is closed at time t-0. A) What frequency radio wave...
